apparent that this mode of driving the rolls greatly impairs theirefficiency as their speed varies in proportion to the speed at which themachine is being run. It being desirable that the cleaning rolls of abronzing machine revolve at a constant predetermined speed independentof the speed of the machine which may be inched or run slow for cer-`tain types of work, it is therefore, an object of this invention toprovide means for driving the cleaning rolls of a bronzing machineindependently of the machine per se.

Another object of this invention resides in the provision of means fordriving the cleaning rolls of a bronzing machine which utilizes theprime mover or motor by which the exhauster is driven. f

With the above and other objects in view which will appear as thedescription proceeds, my invention resides in the novel construction,combination and arrangement of parts substantially as hereinafterdescribed and more particularly defined by the appended claims, it beingunderstood that such changes in the precise embodiment of thehereindisclosed invention may be made as come within the scope of theclaims.

In the accompanying drawing, I have illustrated one complete example ofthe physical embodiment of my invention constructed according to thebest mode I have so far devised for the practical application of the-rand 8. As' the speed at which the cleaning -roll 16 is`-driven, does notaffect the quality principles thereof, and in which The single view is aside elevational view of the gear side of a bronzing machine, partsbeing broken away and in section to illustrate structural details.

Bronzing machinesv of thistype are usually placed so as to receive work directly from the pressoverC S5 v tapes 7 from' whereit is picked up by a bronzing cylinder 8to be carried past a bronzing roll or brush 9 which deposits bronzingmaterial carried in abin or trough 10 onto the P work.--A bronzing padllurubs the `bronze'vo into the work as it passes therebeneath and aseries of cleaning rolls l2 rapidly rotated in atdirection oppositetofthe direction of movement of thev work by means to be laterdescribed,remove he excess bronze which is i5 drawn from the interior ofthe machine by an exhauster 13 through a passage 14.

After `passing the cleaning rolls 12,V the work is Vtransferred from thebronzing cyl-r l inder to a delivery cylinder 15, on which thefo undersurface of the sheet or work is cleaned by af'cleaning-roll 16 beforethe sheet is deposited onto the delivery tapes 17 to be discharged intoa receiving box 18, or delivered in any other suitable manner. "7775 Asisrcustomary, the drive for the bronzing machine is taken directly fromthe press, not shown, with which the machine is used so that thebronzing machine travels at a` speed proportionate to the speed of the#press, the drive being obtained by means of a belt 18 passed about apulley, not shown, carried by the press and a drive pulley 19 fixed to amain drive shaft 20. The shaft 20N is suitably journaled in bearingscarried by the frame 5 and a bearing member 21, and has mounted thereona drive pinionv 22 which meshes'with a'ring gear 23 carried by thedelivery cylinder 15, a similar ring gear 24 lbeing secured to' thebronzing cylinder so that the pinion 22 drives the cylinders 15 of thework, as it merely cleans the under side thereof, itreceives its drivethrough an 9b idler 25 meshing with the ring gear 23 and functionproperly must be drivenr at a con- Gis' depositing bronzing materialonto the work, cleaning means for removing excess bronzing material fromthe work, an exhauster, an exhauster drive, and means for driving thecleaning means from the exhauster drive independently of the drive forthe work carrying means.

The chain37 is also trained about thedrive sprocket 40 of the exhauster 13 andforms substantially a triangle with the sprockets 36, 39 and 40 formingthe Vapexes thereof.

From the foregoing description taken in connection with the accompanyingdrawing, it will be readily apparent tothose skilled in the art to whichan invention or this characterV appertainsthat I provide a drive for thecleaning rolls of a bronzing machine which is entirely independent ofthe drive for the machine per se and one in which the speed of the rollsis at all times maintained at a constant predetermined value to assurethe eilicient operation thereof.
